IMPROVEMENT IN FURNACES AND STVES.

Specification forming part of Letters Patent No. 193,089, dated July 17,1871; application filed March 7, 1877.

To all whom it may concern Be it known that I, JAMES J. JARVES, ofBoston, in the county of Suffolk and Gommonwealth of Massachusetts, haveinvented Improvements in Furnaces and Stoves adapted for burningpetroleum and other mineral oils with safety, and also formaking gas, bymeans of a suitable stove or lamp, constructed according to theprinciples set forth in the following specification, reference being hadto the accompanying drawings.

This invention relates to the 'arrangement and construction of'furnaces, stoves, lamps, and other articles specially adapted forburningmineral oils with safety. As a rule mineral oils are highly dangerous,on account of their explosive nature, where ignited in the ordinary way.

Now, the object of this invention is to provide the means of burning anyof these natural products with perfect safety. Under one form ormodification of arrangement the furnace, stove, or other article,consists of any outer casing of any suitable figure, the lower part ofwhich forms a receptacle for the firep'root safety medium, through whichthe petroleum or other hydrocarbon permeates.

In the lower part of this receptacle is arranged a perforated tube,through which a` stream of oil iiows from the continuous reservoir. Inthis receptacle is placed a quantity of asbestus, which may or may nothe economized by mixing it with a lower stratum of pumice-stone, talc,the silicates of magnesia, or wood-ashes. Or, if preferred, one or moreof these materials may be used without the asbestus, and be appliedgenerally to my furnaces.

Upon the bed of fire-proof material thus formed are arranged one or morevertical tubes, lforming so many chimneys, opening to be heated. y

Near the upper part of these chimneys is arranged a diaphragm orhorizontal partition, which inoloses the contents of the receptaclebeneath. The lower ends of the tubular chimneys are perforated orserrated, to permit the gaseous llames of the burning oils to pass upfreely. These chimneys, as well as the'other below the boiler or othersurface parts ofthe furnace, stove, gas-lamp, or other article,constructed on the principle of this invention, may, if desirable, belined with millboard or slabs or sheets of paper made of as bestus, soas to form a complete protective surface to the metal.

y In this way, when the oil is allowed into the receptacle and isignited, the ventilation is so arranged that it burns with a smotheredame, which serves to heat to a high degree the lower part ofthechimneys, before referred to. The partially-consumed gaseous productsrush through the chimneys and 'are ilashed into flame of great heatingintensity on emergthe entire gaseous product of the oil is utilized andconsumed with safety and economy, either as a heater or illuminator. v

The accompanying drawings show the method of combustion of my invention,which can "be varied and appliedas needed.

A is theN boiler or 'article to be heated; O, diaphragm or partition;D,' tubular inner chimney; E, holes or serrated apertures for gaseousdames to pass into and up the tube; F, fire-proof bed or medium forholding and burning the oil; G, feeding-pipe; H, smothered flames orgases. I Iare doors above and below the diaphragm.

What AI claim as my invention and improvement isl. The combination ofthe receptacle for oils, containing asbestos or other loose fireproofmaterials, the diaphragm, and the chimney, provided at its lower endwith liolesor serrated apertures, and passing upthrough the diaphragm,substantially as and for the purposes described. t 4 A 2. Theabove-described method of' burning hydrocarbon oils and generating gastherefrom by igniting the oils in' a receptacle containing fire-proofmaterials, andemitting the gas through a chimney projecting out ot' thereceptacle, and provided at its lower end with holes or serratedapertures.
